HBM's CTS/CTM series of current transducers feature industry-standard, fluxgate, closed-loop technology. The second harmonic zero flux detection ensures the highest accuracy and lowest drift. With the high-bandwidth support, they can be used with fast rise time signals, such as those found in electric drives or other inverter-based power applications. The 1U rack-mountable interface unit can support any mix of up to six CTs.
Highest possible accuracy – for AC or DC signals
Easy to Use – mounted in minutes
Reliable operation – advanced EMC and overload protection
Broad range from 50 A rms to 1200 A rms
1 or 2 ppm accuracy
- 40°C to + 85°C operating range
Complete solution with interface unit, connection cables and burden resistors
Interface unit to power and support up to 6 transducers
